Hypertension is also reduced by Magnesium, Vitamin K, Omega-3, CO-Q10, and garlic

It appears that the above supplements can be used concurrently with Vitamin D to massively reduce hypertension

Hypertension is reduced even more in people having vitamin D health problems
Perhaps to Vitamin D gene limitations?

Research has shown that people with higher vitamin D levels are more likely to have lower blood pressure and are less likely to develop hypertension.

Studies have shown that taking a vitamin D supplement can reduce blood pressure in people with hypertension.

Some research has shown that taking a vitamin D supplement helps regulate the blood pressure system in the body.

However, not all trials show reduced blood pressure after taking vitamin D.
This means that we can’t say for sure if vitamin D is a main factor in preventing hypertension or in lowering blood pressure.

Role of Vitamin D supplementation was studied in patients with hypertension.
One hundred hypertensive patients (group I) were given conventional antihypertensive drugs while another 100 patients (group II), in addition, were supplemented with Vitamin D(3) (33,000 IU, after every 2 weeks, for 3 months).

Besides diastolic and systolic blood pressure, serum calcium, phosphorous, alkaline phosphatase, albumin, albumin-corrected calcium, and 24 h urinary creatinine levels were estimated in both the groups before the start of treatment and after 3 months.

Vitamin D supplementation showed a more significant decrease in systolic blood pressure.
This group also showed a significant increase in serum calcium as well as albumin-corrected calcium with a decrease in phosphorous.
Results of the study confirm that Vitamin D supplementation has a role in reducing blood pressure in hypertensive patients and that it should be supplemented with the antihypertensive drugs. More extensive studies with a larger group, to draw a definite conclusion, are in progress.

Letter to the Editor: Prehypertension: To Treat or Not To Treat Should No Longer Be the QuestionWe read with great interest the article by Selassie et al1 that progression from prehypertension to full-blown hypertension occurs more rapidly in blacks, with 50% transitioning to hypertension within 1.7 years compared with 2.7 years in whites. Although the authors highlight the importance of controlling prehypertension, we feel that the authors missed an opportunity to stress the feasibility of using antihypertensive drugs to control prehypertension. As we argued previously,2 the recommendation by the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure to treat prehypertension only with lifestyle changes3 is unlikely to work. Our view that prehypertension should be treated pharmacologically is supported by a recent meta-analysis of 16 trials involving 70664 patients.4 This analysis found that prehypertensive patients randomized to the active treatment arm had a 22% reduction in the risk of stroke as compared with the placebo group. In addition, treatment of prehypertension with an angiotensin receptor blocker reduced the risk of incident hypertension.5 Thus, the debate of whether to treat prehypertension should end. Treating prehypertension is medically sound and economically viable,2 and benefits of treatment are now apparent.

Nondipper hypertension is associated with increased cardiovascular morbidity and mortality. Vitamin D deficiency is associated with cardiovascular diseases such as coronary artery disease, heart failure, and hypertension. Vitamin D deficiency activates the renin–angiotensin–aldosterone system, which affects the cardiovascular system. For this reason, a relationship between vitamin D deficiency and nondipper hypertension could be suggested. In this study, we compared 25-OH vitamin D levels between dipper and nondipper hypertensive patients. The study included 80 hypertensive patients and they were divided into two groups: 50 dipper patients (29 male, mean age 51.5 ± 8 years) and 30 nondipper patients (17 male, mean age 50.6 ± 5.4 years). All the patients were subjected to transthoracic echocardiography and ambulatory 24-hour blood pressure monitoring. In addition to routine tests, 25-OH vitamin D and parathormone (PTH) levels were analyzed. All the patients received antihypertensive drug therapy for at least 3 months prior to the evaluations. 25-OH vitamin D and PTH levels were compared between the two groups. No statistically significant difference was found between the two groups in terms of basic characteristics.

Wikipedia on Hypertension dipping at night - May 2012Ambulatory blood pressure monitoring allows blood pressure to be intermittently monitored during sleep, and is useful to determine whether the patient is a dipper or non-dipper--that is to say whether or not blood pressure falls at night compared to daytime values. A nighttime fall is normal. It correlates with relationship depth but other factors such as sleep quality, age, hypertensive status, marital status, and social network support.[2] Absence of a night time dip is associated with poorer health outcomes, including increased mortality in one recent study.[3] In addition, nocturnal hypertension is associated with end organ damage[4] and is a much better indicator than the daytime blood pressure reading.See also VitaminDWiki Hypertension which remains high (nondipper) is associated with low vitamin D – Sept 2017

Objective: In the northern hemisphere vitamin D deficiency is highly prevalent during winter months, and observational studies have associated hypertension with poor vitamin D status. We tested the hypothesis that vitamin D supplementation in the winter lowers blood pressure (BP) in patients with hypertension.

Design: Randomized, placebo-controlled, double-blind study.

Method: 130 patients with hypertension were randomized to a daily oral dose of 75 ug cholecalciferol or placebo for 20 weeks. The study population consisted of Caucasians residing in Denmark at the 56th northern latitude. Baseline examinations took place from October to November where cutaneous vitamin D synthesis is absent. Primary endpoints were 24-h ambulatory BP, pulse wave velocity (PWV) and central BP obtained by applanation tonometry. Other endpoints were p-25(OH)D, p-Ca++, p-iPTH and components of the renin-angiotensin system. Plasma concentrations of renin, angiotensin II and aldosterone were measured using RIAs. Data were analyzed using unpaired t-test and Mann-Whitney test when appropriate.

Conclusion: In hypertensive Caucasians residing at the 56th northern latitude, 75 ug of cholecalciferol daily during winter months caused a significant reduction in central systolic blood pressure. In a sub-analysis of patients with p-25(OH)D <75 nmol/l, a marginal reduction in both systolic and diastolic 24-h ambulatory BP was observed.
